HORSESHOE-MACHINE.

` Specification of Letters Patent No. 31,941, dated April 9, 1861.

To all whom it may concern:

Be it known that I, D. N. ALLARD, of Mc- Connelsville, in the county ofMorgan and construction and operation of the same, refi erence being hadto the accompanying drawings, making a part of this speciiication, inwhich- Figure 1, represents a perspective view of the machine. Fig. 2,represents a longitudinal vertical section through the die blocks, andbevel geared wheels that roll the dies against the blank or shoe.

My invention consists in so combining two die wheels, the aXes of whichare at right angles to each other, and gearing and operating thelntogether, as that each and every revolution of said die wheels shallform a horse shoe, and tip it up, or loosen it from the die, so as to bereadily removed, and allow another blank to be introduced. Said horseshoes being not only bent" into form, but upset and swaged out intoproper shape, and if preferred, at the same time creased and punched.

To enable others skilled in the art to make and use my invention, I willproceed to de- `bed E is arranged a second bevel wheel F,

that gears with, and is turned by, the bevel gear O; and on this wheel Fthere is a die block G, which, as well as the die block D, are maderemovable so as to change them when larger or smaller sized shoes are tobe made, each size of shoe, having its own dies, but the wheels mayreceive any ordinary number of sized dies.

Motion may be communicated to the wheels C, F, through a crank H, andgearing I, J, or by a belt or band, or in any other well known way. Orthe first moving power may be applied to the shaft of the wheel F, ifmost convenient to do so.

On the wheel F beside the die block, there is placed a tipping bar K,that has a projection a upon it, by which it is pivoted or hinged to thelugs b; the points or heels of the shoe rest in the recesses c, c, inthis tipping bar, and when the bar is thrown up, by

a cam on the wheel C, striking the projection a, it throws up or loosensthe shoe from the die, and `makes it easy of removal.

The die block on the wheel F, is of simple form its center portion fgiving shape to the interior of the shoe, while the other parts d, e,form the heel and toe of the shoe-the heels being narrowed up andthickened, while the toe portion is spread out, and made thin. The otherdie blook D, is more intricate in form. Its marginal line g travels onthe center portion f of the die block F, and its other cam-line h movingagainst the outside z' of the said die block F-so that the blank isupset or swaged out so as to completely fill up the space between thelines f, z', and g, l1., and this space is the exact form of a well madehorse-shoe, handsomely and neatly drawn out. It is not simply a bentblank, but a handsomely wrought shoe.

Oreasing dies 7c, and punching dies Z, may be connected with the dieblock o, so as to complete the shoe at a single operation, or, ifpreferred the creasing and punching may be done on a separate machine.

A plane through the die block D, would show a true circle, while a planethrough the other die block F, would represent a portion of an ellipse,and to cause this circle to travel over the ellipse, the cam block D, iscut away as shown in the drawing, to make its line, if spread out, ofthe same length of the ellipse, or line around the ellipse.

The heel portions m m of the shoe, are formed, or rest, in the recessesa, n, of the tipping bar K, so that when said bar is tipped up,.by thepart o of the cam block D, rolling over it, it will throw up the shoe,and thus loosen or remove it from the die.

Underneath that portion of the wheel F wherethe pressure or strain comesin bending, upsetting, and swaging the shoe, there is a friction andsupporting wh'eel, to prevent said wheel F, from yielding.

In using the machine, one end of the blank is laid in one of therecesses n of the tipping bar K, and by the revolving of the dies, it isimmediately caught and pinched between said dies, which also` bends itaround the die block G, which gives it shape, while the dies swage itinto form.

The tipping bar K, performs three functions-it is a gage for insertingthe blankit is a die for forming the heels of the shoe, and is aloosening or delivering device, for raising the finished shoe from thedie block. `rIhe blank is cut from a flat bar of suitable size, and isWrought into a shoe by being compressed and drawn down between the dies.

I have represented the die Wheels-one as being vertical, and the otheras horizontal. It is obvious that they may be inclined in any mannerthat Will leave their shafts or axes at right angles to each other; andthe one that moves over the blank may have a slip motion, so as to upsetaswell as compress the blank. By slip motion, I mean allowing one die algreaterspeed than the other, which may be done by simply cha-nging` thecomparative diameters of the gearings, or of the dies.

Having thus fully described the nature and'obj ect of my invention, andshown how the same is operated, what I claim therein v as new and desireto secure by Letters Patent, is-

1. The combination of a vertical and a horizontal Wheel Workingtogether, and fur-V D. N. ALLARD. y
